Battery Health Management on Mac - Extends battery life on MacBook

In the latest update of macos catalinaVersion 10.15.5 brought a very important feature for the owners of MacBook. A system of analysis and management of energy resources Mac, in order to extend battery life.
It is known that batteries with lithium-ion technology are the most advanced at this time. They charge quickly, last a long time in use and have the best charging technology for devices. Over time, their performance begins to decline. Battery life decreases, and at some point this MacBook consumable will need to be replaced. After all, we are talking about the only consumable component of Mac, iPhone, iPad, AirPods or any other device that uses batteries / accumulators, on which time (chemical aging) and how to use it leaves its most obvious imprint. The longer a MacBook battery is used, the lower its performance will be.

I've written about it in the past MacBook batteries in "Proper usage and battery life on your MacBook / MacBook Pro"And"How used is the battery of a MacBook, MacBook Air or MacBook Pro (Charging Cycles)

This feature of "Battery Health Management”Introduced on macOS Catalina 10.15.5 is not a novelty in the Apple ecosystem. The options have been present on the iPhone for some time "Peak Performance Capability"And"Optimized Battery Charging", Which aim to extend battery life.
Option Battery Health Management it's not much different.

Battery Health Management - What it is and how it extends the life of your MacBook battery

This feature will collect data about usage behavior si loading of the MacBook battery. Cycles and battery charge / discharge level, battery temperature history and charging mode. Based on this collected data, a custom optimization will be made. With the function Battery Health Management activated may reduce the battery charge level, to avoid its chemical degradation. Basically they will be fewer charging cycles. In terms of user experience, it will be available shorter MacBook usage time when it is not next to a power supply.
Note that Battery Health Management will extend the battery life only in the scenario in which you have get in the habit of charging your MacBook several times a day.
If MacBook it is always connected to a power supply, with 100% battery, then it is highly recommended to deactivate Battery Health Management. In this scenario the effect will be reducing battery life, because if a MacBook is kept permanently connected to the power source, reached 100%, the battery will no longer be charged.

Function Battery Health Management is present on all MacBook devices with Thunderbolt 3 USB-C port and is automatically activated after updating macOS Catalina or when you install the latest macOS operating system. So, if you have updated to the latest version of macOS, and Battery Health Management will not help, it is good to disable this feature.

The new function can be found in “System Preferences"→"Energy Saver"→"Battery Health.. "

Click on "Battery Health.. ”, uncheck the option“ Battery health management ”, then in the dialog box that will open, click onTurn Off"

Once this option is deactivated, the battery usage behavior will no longer be monitored and it will not be optimized in order to extend the life time.
If you are a person who is always on the move and making chaotic loads of your MacBook, it is good to leave this option active.
